Sps die off

[Bernal]

Hi,
For you sps lovers I’m in new to sps and to posting .I have been getting new growth/ white tips. With the new tips I see there white then they start turning brown is this normal? Currently in the 230 par range area TIA

Phosphate is pretty high

Thanks I’m currently using phosphate RX I few drops and testing.

Acros turning brown is typically a nutrient issue.

In nutrient rich water zooxanthellae turn to their natural colors, which are usually drab brown. Slowly lower your PO4 and they should look better, slowly is the key word here.

The description of new white tips turning brown makes me think algae took hold on some burnt tips.. Might be helpful to post a picture from the top down so everyone can see the tips.

Cool looking tank!

This pic isn’t growth. That’s die off

i agree.
You might want to retrace what’s been going on or how quickly your dosing

Thanks for all the help everything I’ve learned so far is online. Sounds like a need a mentor then more sps.lol

Looks like good old stn

causes? How old is the tank? Flow? Alk swings? Nutrient swings? The joys of acros 😂

13 months old Waterbox 130.4 - 2 mp40 s on each end for flow.alk steady at 9.4.

Those pics help, agree that's TN. Two things stand out to me, low light and high nutrients will cause this. If you're going to keep higher nutrients, then you better crank the lights and flow to match. But that is oversimplifying a bit. A couple of things that you can do slowly that will help in the long run. First, slowly bring down PO4 and alk (8-8.5) and slowly turn up your lights. Certain bacteria will help, I like using PNS Probio for reducing PO4, but I would use half the recommended amount until you get to 0.1ppm of PO4. When increasing lighting, you need to increase flow to help the sps in removing waste and provide o2. If you're not using macro algae on a reverse light cycle, then I would seriously consider setting something up. Just curious, but did you start this tank with dry rock?

Thanks for your knowledge I will lower phosphate. I did start the tank with dry reef rock I do run a chetto
With a paxbellum n18 which I removed some heavy dense chetto today.

Yeah I agree unfortunately that is die off. The white is bare skeleton, the brown is new algae growth. Personally I'd stop the liquid phosphate remover. Start to try to figure out where all your excess po4 is coming from. Do you have a decent sized skimmer for the system? What is the main type of food you are feeding the fish? Any other additives?

Also, what is your source water?

Water change/maintenance schedule?

Yes I have the royal exclusive 160 .I feed twice a day seaweed extreme small size sinking pallets on a feeder roughly 10-15 pallets every feeding and a cube of frozen every night .I do water changes on a average of every 2 months.rodi from local lfs .
